blockchain is an over-rated technology

What is the most expensive product in human being history? Nevertheless, credit.

The intelligence creature is self-centred. That is why all other human relatives, such as Neanderthals and Sapiens, extinct from the earth. Even in modern civilized world, the trustiness between races is still hard to be sync in the same level.

There is a sad story in scientific fiction ‘Dark Forest’ which said galaxy is forest and each civilization is a hunter, conflicting is inevitable due to mistrust.

Now here comes a new solution — blockchain. The first time human beings have a way to corporate in a de-centralized network.

Blockchain theory is simple:
Show who you are
Show what ability you have
Sign at the end of chain

Aha, based on blockchain, government removed, boss disappeared. How thrilled !

But after practising a couple of months, some serious concerns are raised.

The first crisis is from efficiency, the guy would verify his ability with protocols like POW (Proof Of Work). POW does waste energy without any production.

The second fault is the limitation of volume. Yes , Byzantine General problem can be resolved by blockchain. But this case has 10 generals. Maybe 100, 1000 is okay. If furthermore, 1 million, 10 million, 1 billion … not likely to listen clearly surrender by so much noises.

Basically blockchain opens a gate for an endless hole.

How far we are able to dig into is not forecastable.
